This paper presents the performance of a focal plane array operating in transmit mode at 30 GHz for use in future Very Small Aperture Terminals (VSAT). The performance of the array is analyzed in front of a reflector with a small F/D ratio. The focal plane fields are synthesized using an array with aperture-coupled microstrip antennas. This configuration is used to determine the optimal excitation coefficients. A Silicon transmitter integrated circuit (IC) using a phase shifting up-converter operating at 30 GHz is designed and measured together with the antenna to generate a complex gain constellation for the required beam steering. The experimental results are used to calculate the far-field pattern of the complete system.
